## What the Geo Fencing API does

The Geofencing API evaluates an IP address against geographic boundaries you define and reports whether it falls inside or outside them.

Geographic controls are a blunt but effective risk tool. Blocking or flagging access from outside the regions you serve removes a large volume of automated abuse before it reaches your application logic.

## Where teams use the Geo Fencing API

1.  Restricting access to the regions a service operates in
    
2.  Flagging logins from unexpected locations
    
3.  Enforcing regulatory geographic restrictions
    
4.  Adding a location signal to a fraud model
    

## Frequently Asked Questions (FAQs)

How accurate is IP-based location?

Reliable at country level and reasonable at city level, but not precise. Treat it as a signal, not proof of where someone is.

Can it be evaded with a VPN?

Yes, which is why it belongs alongside other signals. IP Quality Check helps by flagging addresses associated with VPNs and proxies.

How are boundaries defined?

You specify the geographic areas relevant to your policy and evaluate addresses against them.
